CHAPTER 5 POLYMER STRUCTURES PROBLEM SOLUTIONS
Since this is an alternating copolymer we know that chain fraction of each repeat unit type is 0.5; that is f s = f x = 0.5, f s and f x being, respectively, the chain fractions of the styrene and unknown repeat units. Also, the repeat unit molecular weight for styrene is m s = 8(A C) + 8(A H) = 8(12.01 g/mol) + 8(1.008 g/mol) = 104.14 g/mol

Nitrile rubber can be classified as three types based on the acrylonitrile (ACN) content (low, medium, and high). Resistance to aromatic hydrocarbons is higher as ACN content increases.
